SPECIFIGATION forming part of Letters Patent N0. 271,642, dated. February 6, 1883.

Application filed August 24, 1882.

T all wh0m it may concern:

Be it known tllibl; I, JACOB LAUTH, of Milwaukee, in the county of Milwaukee and State of Wisunnsin, have invented certain new pnd usei'ul linpioveinents in Tbill Couplings, of whch the. following, in connection With the ac- C0lll )lli \lllgg dmwings, is 21 specification.

In the (liuwings, Fignre 1 is 21 top 01 plan view of i thill-cnupling emhod ying lil) inventi0n. Fig. 2 is a section in the plane of the line 00 nv of Fig..l, aml Fig. 3 is u perspective representat1on 0t' the coupling provided with in improwments.

Like letters 0l' reference in licate lik e pmts.

A represents the axle.

B is the clip. 'lhis clip consists of twn p2nts, (661. The rem part: of the part a isconneutetl and 'orrns part of the strap b0f the clip,

' ing the top of the part; a.

and which passes over tbe axle, as shown. The nrwanl ends of the pa1ts a and a are hinged t0 ezich othe1 so that the pari; a maybe swung upward to receive the cross-holt of the Lhill-iron, the pnrts en nml a being adapted, as shown at 0, to reqeive the said bolt.

0 is the thill iron 0r srnp, and D is ts bolt or conpling-pin.

E is d; latch 01 catch pivoted to the clip. The upper fuce of the part a/ has attached to it; L spring, I, an l al is cntj awny 01 sunken underneath the 'ree end of the said spring, s0 as to permit that end to have some wertical play '01 mnvement, ns imliuated in Fig. 2.

d is a small pin er stad on the spring F.

G is a plate covering the spring F ind formihe s;ud cl passes freely through the plite Gr. The plate Gr and lhe part a 'cLIG s0 out: away as to permi the lower end of the Iatch E to extend. somewhaz ed in its place in the coupling.

(No model) bel0w the spring F and plate G when the said latch stands vertically, as shown, and al: which time the said spring, when free or not depressed, l0cks the said latch in its vertical position, and the said latch in turn then locks the part a in its closed position.

T0 apply t he thills, l depress the Spring F hy pressing down slghlly up0n stud d, which i'eleases the latuh E, which 1 thon turn or swin; into a horizontal position. The part a n1ay now be raised to allow the holt D to be insert I then close the part (6 and return the latch E tu its verti- Cll position, when the t-hills will be loeked 0r held firmly in the conpling. T0 remnve the thills, ldepress the stu l r], swing the latch E laterally,aml misethe puta'. B y these means the thills llly he atmched and removed with great facility, iiul they are also efctually prevented from being ucuhlentnlly (letachetl.

Having films (lescrihed 1ny iuvention, what I claim as new, and lesire to secure by Letters Patent, is-
